Thread: 2stroke outboard

https://www.maritimenz.govt.nz/conte...onal-boats.pdf

That's the maritime nz hot sheet.

It's an interesting argument, 4s uses less fuel at idle than two stroke - that's where I think they calculate the better environmental efficiency. But if you're travelling at full speed for the majority of the time?

Also the greater weight of the engine itself requires more energy expended to get on the plane, everything else being equal. A long-ish lead time and most of the affected engines will be consumed by the expiry date anyway. I'd also have no idea how they'd police this, considering there is no registration system for recreational boats in NZ...
